Hmm. Blind people called dogs, because they have to use their nose instead of their eyes?
Not sure how that's funny though.
Makes me wonder, dogs supposedly have evolved to be better companions of humans, and lateral gene transfer is a thing. I wonder of they had much poorer sight 7k years ago, or perhaps, a popular local breed did.
(Naturally, to support my blind hypothesis, and walking into a bar instead of seeing it)
I love reading the posited explanations for that joke in academia and when it’s posted randomly people usually have a stab at it too.
